(e.g. epibenthic)

Inhabits exclusively clear-water rivers. Juveniles measuring about 2.0 cm SL occur in small brooks with sandy bottoms and patches of leaf litter. Observed searching the bottom substrate for small invertebrates and detritus by picking up and turning the leaves. Collected only in very soft water (no detectable hardness) with high acidity, pH value mostly less than 4 (Ref. 85095).
